Have you recently had a new furnace installed and are now experiencing a strange smell? You’re not alone, because a lot of other homeowners also experience this at first. Let’s review what’s causing this smell, and when you can anticipate it to subside, as well as three other furnace smells you shouldn’t neglect.
Why Your New Furnace Smells
There are two explanations why a new furnace might smell.
Your furnace has a special application on some parts to keep them from rusting. This may include the heat exchanger, which safely exhausts gases including carbon monoxide naturally made during the heating process.
When your furnace runs for the first couple of times, the coating may give off a burning smell. This is normal and the smell should dissipate the more your furnace heats.
To be on the safe side, you’ll want to contact a heating and cooling company if the smell persists. A burning smell that remains can mean the motor has overheated or there’s an electrical problem, among other issues.
Dust accumulates inside your furnace when it’s idle in the summer. That dust will burn off when you flip on your furnace in the fall, producing a burning smell. This smell should go away within a few minutes.
One way you can reduce or prevent this smell is by having furnace maintenance done every single year. This is needed to keep your valuable manufacturer’s warranty good, plus it keeps your furnace clean and ensures it will run smoothly during the upcoming heating season.
3 Other Furnace Smells You Shouldn’t Disregard
While it’s less common for a new system to require furnace repair, it can happen. Here are three other scents you should watch for and what they might mean.
- Burning plastic or rubber. If your furnace smells like burning plastic, you might have an electrical difficulties. Electrical wiring is protected in plastic to prevent shocks, and this smell is an indication that heat is melting this protective coating. To hinder a fire, switch off your furnace as soon as possible and have it checked out by an HVAC technician.
- Gas or rotten eggs. Gas companies add sulfur to natural gas to alert you when there’s a leak. If your furnace smells like gas or rotten eggs, shut it off as soon as possible, get out of your home and call 911. Exposure to natural gas can make you sick, plus it’s highly flammable and explosive.
- Musty. If your furnace smells musty, you might have mold and mildew growing in your ductwork. We recommend having your ductwork examined and cleaned if needed.
